T0 aZZ 1071/0110 if; vim-y concern.-

Be it known that I, FLETCHER W. IlEWEs, of Bloomfield, in the county ofEssex and State of New Jersey, have invented a new and usefullm n'ovement in lndexing-hiiachines for Books, of which the following is aspecification.

Myinvention relates to machines which cut in the edges of a book aseries of nicks to mark predetermined divisions of the work andfacilitate ready opening at such places, such as the one for whichLetters Patent of the United States N o. 345L175 were granted tome,dated June 9,1886, and upon which my present invention is animprownnent.

The present invention consists, in general, of the following improved.devices as applied to a machine of: that character: a descending rotarycylindrical knife making a shearing cut; the pivoted table for the bookmade adjustable to different inclines to accommodate books of variousthicknesses; adjustable shaping-stops near the knife to shape the edgeof the book, so that the nicks may be uniform and suited to thethickness of the book: a movable cutting block and mechanism to drop thesame after each cut to remove the chips and allow the colorcr to enterthe nick; a positive cscapement device consisting of cam-groove androcking bar with racks and ratchets to govern the movement of thebookcarriage down the incline; an improved col.- orer by which the coloris supplied to the nick and improved mechanism to operate it; adjustablebook holders or clamps to hold the book to the carriage; mechanism bywhich power is intermittently applied to operate the machine, andvarious details and combination,

the belt-tightening device from opposite sides and in oppositepositions, the rear view of Figs. 5

which is seen to the left in Fig. 3.

and 6 are a top and side view, respectively, of the coloring mechanism,also shown in Fig. 2. Fig. 8 is a perspective View of the book holder orclamp sliding upon the top of the book-carriage and to be placed oneeach side of the book. Figs. 1% and 15 are end and rear views,respectively, of another form of book-clamp. Fig. 9 is an end view ofone of the pair of shapin -stops. Fig. 10 is a rear view of theescapement device, of which other views are shown in Figs. 1 and 2.Figs. 11 and 12 are sectional views of two forms of the knife. Fig. 13is a side view of mechanism to operate the machine by hand instead of bypower. Figs. 16 and 17 are figures showing the adaptation of the machineto the purposes of a label-cutter.

The main frame of the machine, Figs. 1, 2, and 3, consists of the partsA, l3, and H, A being the sides, B an upright frame-work connecting thetwo sides A, and the top of which forms the cutting-table Z) for theedges of the leaves to rest upon while under the knife, and H a furtherupright extension to which the knife operating parts are connected.

The knife m is cylindrical, and is carried at the lower end of a shaft,m, Fig. 2, which, as it revolves, also moves up and down by means of thescrew m upon the shaft m, gearing with the thread in the nut H which isbolted to and thus forms a part of the frame H.

Referring to Fig.:. 2 and 3,) is a puiley which receives power from thebelt and whose shaft j turns in hearings in the brackets 7t, affixed tothe frame B. The side upon which the pulley j is attached I shall callthe rear of the machine, and that upon which the operator stands thefront. The crank-arm 7' is attached to the end of the shaftj and itsconnecting-rod is pivoted at the other end to the cranlearm a. Thecrank-arm i is affixed to the shaft a turning in bearings in the frameH, and having affixed to its opposite end the sector bearing a segmentalgear. The crank-arm a is longer than the crank-arm 7' so that therevolution of the crank-arm j simply oscillates the crank-arm a and thesector a. The gear upon a gears with the gear-wheel the sector a whichis held vertically in the frame H, and mounted loosely upon the shafton. A feather, a, fast upon the interior of the gear-wheel a, fits intothe 'feather-way m in the shaft in, Fig. 2, so that the rotation of thegear-wheel 20 serves to rot-ate the shaft m, and also, by means of thescrew m to send it up and down through its bearings II and ll" in theframe H, the shaft m passing freely through the gear-wheel a.

In the drawings theknife is represented at about its highest position.If new the pulley j be turned in the direction indicated by the arrow,the motion transmitted through the parts just described gives for a halfrevolution of the pulley j a combined descending and rotary motion ofthe knife. This cuts from the edge of the book lyin under it the nickdesired, completing the cut as the crankarm it reaches its high estpoint of oscillation. The reverse motion of the crank-arm uthat is, theremainder of the revolution of the pulleyj-carries the knife back to itsoriginal position.

The improvement over the knife specially described in my prior patent,hereinbefore referred to, is that a descending knife cutting against astationary cutting-block makes a cleaner out, especially in soft spongypaper, while its rotary motion enables the cut to be made with much lesspower than if the knife were simply forced down without rotation.

The improved book-carriage, (upon which the back part of the bookrests,) with its connecting parts, is shown in Figs. 1 and 2.

O is the carriage, consisting of two parts, and c, which are hingedtogetherhorizontally at one end, 0 and at the other are separated by theadjustment-screw c. The under part, 0, slides upon the inclined plane,being kept thereon by a dovetail or in any other appropriate way, andthe back part of the book rests upon the top of the upper part, c, whichshould be parallel with the table I) at all times, and substantiallyupon a level with it when the carriage is at the top of tl'leinclinedplane. Aweight, 1), whose cord passing over two rollers, p and p andthrough a groove in the under side of the part in two places, 0, isattached to 0 near the hinge 0 tends continuously to draw the carriagedown the inclined plane.

The inclined plane 6 is hinged horizontally at e to the part E, andthese parts, with the carriage 0, form an oscillating table, by whichthe book, which is clamped thereto, may be alternately withdrawn fromand brought up to the knife. The adjustm'ent-screwe allows theinclination of the inclined plane 6 to be varied at will. The open spacebetween the oscillating table, which supports the back of the book, andthe cutting-table 1), upon which its edge lies, gives a space into whichthe cut leaves may hang down, as explained in my prior patent. A shield,0, attached to the carriage O, prevents the falling chips from cloggingits parts and protects the cut leaves from injury. In the two sides ofthe frame A are horizontal slots a, Fig. 2, in which rest the ends of abar, D, Fig. 1. This bar D forms the support for the oscillating part E,with the inclined plane e and the carriage C, and also for thestationary piece F. It is adjustable to different positions in the slotsa, in order to accommodate books of various widths, but is stationaryduring the operation of cutting and coloring. The oscillating table isdesigned to stand upright during those operation s, and then, by thehandle 6 or other suitable means, to be swung toward the operator,bringing the book away from the knife. In swinging, the oscillatingtable turns upon the pivots (Y, which project inward from the angles ofthe bar I). A stop, (1, fastened to the barD, or to any other convenientpart of the machine, limits the movement of the part E toward theoperator. At each oscillation of the part E upon its pivots (l thecarriage C is moved a certain distance down the inclined plane by thefollowing mechanism.

Attached to the bar D is the stationary upright piece F, having in. itsupper portion the cam-groove f To allow of vertical adjustment in orderto suit the adjustment of the inclined plane 6, the stationary piece Fis carried upon a pin rising from the bar D, and fastened thereto bymeans of the set-screw f. Affixed to the lower pai t, c, of thecarriage, and forming a part of it, are two similar racks, q, one oneach side of the carriage and opposite each other, with their teethprojecting below the part c. The teeth of one rack are placed oppositethe intervals of the other, and they engage, respectively, with thecatches i? of the escapement device, which is attached to the inclinedplane 6. The escapement device, Figs. 2 and 10, consists of a hanger orbar, 1', projecting from the under side of the inclined plane c, andhaving at its lower end a pin, t", upon which is pivoted a rocking bar,The upturned ends of the rocking bar carry a shaft, 11 to which areaffixed the two catches 2, extending upward on each side of the carriageO and engaging with the racks q. At one end of the rocking bar 2' isaffixed at a right angle a pin, i designed to fit into and traverse thecam-groove f The escapement device is so constructed that the catches ican be turned down (to the right in Fig. 1) out of connection with theracks. The plate 1' forms the upturned end of the rocking bar i andalways stands upright. The plate 5 Figs. 1 and 2, is rigidly attached tothe shaft which carries the catches. Between these two plates 1' and 1'lies a handle-bar, i loose at one end upon the shaft having a slotthrough which the shaft i passes. The handle-bar i is held in theposition shown by a pin, i", affixed to it, which enters a nick in theplate 2', Fig. 10. This pin on the other side of handle-bar i Fig. 1,passes through a slot in the plate 1 and has a spri1ig, i, connecting itwith some fixed part. If the pin i be withdrawn from the nick and thehandle-bar i turned to a perpendicular position until the pin i strikesthe IIO shoulder i the plate i is carried with it, and the catches't"thereby turned down out of connection with the racks q. 1

The operation of the book-carriage is as follows: The cuts in the bookare to be made in succession from right to left, the carriage movingfrom left to right. The book is placed upon the top of the upper part ofthe carriage, c, and held there by the clamps, hereinafter described, insuch position that the first cut will be made in the proper place uponthe front edge, which is supported by the cuttingtable 1) immediatelyunder the knife m. The operator, after makin the first cut, oscillatesthe table e toward him, and by means of that movement the pin of theescapement de vice traversing the cam-groove f releases the rear catch,i from its rack and brings the other into engagement with the oppositerack,

thereby allowing the carriage O to be drawn by the weight p down theinclined plane for a distance of half the interval between thesuccessive teeth of one rack. Vhile the part E rests against the stop dthe operator finds the place for the next cut, and then returns the partE to its upright position, thereby earrying the pin back through itscam-groove and allowing the weight p to move the carriage (l down theinclined plane the other half of the interval between two teeth. Thedistance between. two cuts will be exactly the distance between twoteeth of a rack. One or other of the catches i is always in engagementwith one of the racks. Different spacing may be provided for by means ofdifferent sets of racks. When one series of cuts has been made, thecatches i may be turned down out of connection with the racks, as beforeexplained, and the carriage O pushed up to the top of the inclinedplane. The in'iprovement of this escapement devieeover the one shown inmy prior patent is that its action is more positive and sure.

as explained in my prior patent, to compensate between each cut for theincreasing number of leaves lying below the level of the cutting-tableZ), and thus allow the leaves to be cut to extend from the carriage C tothe cutting-table h horizontally, or nearly so, in order to produce aneven cut. Different books require different inclinations, according tothe thickness of the book. The proper incline for the desired verticalinterval between. the first and last cuts of one series having beendetermined, the inclined plane 6 is then set at that inclination by thescrew 6 and the top of the carriage is leveled by means of the screw 0.The stationary part F is then adjusted vertically to correspond.

An additional feature in this machine eon sists of the shaping-stops anear the knife, Figs. 1, 2, and 9. They consist of upright pieces(straight or curved in vertical section) extending along the rear edgeof the table 1) upon each side of the knife and inclined toward theoperator. Their object is to shape the edge of the book as it ispresented to the knife, holding back the edges of the upper leaves ofthe section to be cut, so that the successive segments of paper lyingunder the knife increase in size from the top tothebottom of the cut.They thus cause the cuts to be uniform, whatever the shape of the edgeof the book, Whether straight or rounded. They are made adjustable intwo directions. An angle-plate, n, Figs. 3 and 9, is affixed to the backof the shaping-stop a and has in it a small curved slot. Anotherangle-plate, n is affixed to the rear of the table 1') and has in it asmall horizontal slot. A bolt, n, passes through both of these slots andhas a thumbnut upon the outside, by which the two angleplates may befixed in any position. The horizontal slot in the an gle-plate n allowsthe shaping-stop nto be adjusted forward or backward on the table Z) tomake a shallower or deeper cutthat is, to cut less or more from eachleafand the circular slot in the angleplate n allows the inclination ofthe shapingstop a to be adjusted in order to allow the knife to cut fewor many leaves. Those adjustments allow the same shaping-stops to beused for both thick and thin books and those requiring few or many cuts.The two shaping-stops maybe united inone piece for ease of alignment orother reason.

The improved coloring device to apply coloringdluid to the surface ofthe newly-made cut is shown in Figs. 2, 5.3, 5, and o. It conof acolor-bag, o, from which the ink. or coloring-fluid is led to a smallcylindrical block, 0, covered with cloth or other porous material, so asto retain a quantity of the fluid upon its surface. The colorer 0' isshaped to fit the nick, and is attached to a carriage, 0 which slides inways upon the bracket 0*, affixed to the framelll. It operatesautomatically in connection with the knife.

The cam-rod o, by which it is operated, is The object of making e aninclined plane is,

pivoted at its upper end to the sector a and extends downward between aroller or pin, r, Figs. 5 and f, attached to the side of the slidingcarriage 0 and another roller or pin, r, attached to the bracket 0. Thispin. 1: may be made adjustable, or may be held toits work by an adjustable spring pressing it forward, so that the amount of pressureexerted upon the surface of the cut by the colorer 0 may be regulated byadjusting such spring. \Vhile the knife is operating the cam-rod 0, Fig.2, rises from the position. shown and the colorer remains stationary;but the return movement of the sector It carries the cam-rod 0 downuntil its cam, bearing upon the pin r, (as soon as the knife has risensuliieiently,) carries the sliding carri age o forward upon its ways andthe colorer 0' into the cut directly under the knife just as the knifereaches its highest point and the sector a completes its backwardoscillation. The cam-rod then rises immediately by means of the forwardoscillation of the sector 2!, and the spring r Fig. 5, attached to thecarriage and to the bracket,

IIO

brings the colorer back as the knife descends to make another cut.

The color-bag 0, Figs. 5 and 6, rests upon a support hinged to thesliding carriage and a link r pivoted to the bottom of this support andto the rear of the bracket 0 compels the color-bag, as the carriage 0 iscarried forward, to rise above the level of the tube 0 thereby causing aflow of ink to the colorer 0'. As the carriage moves back, the color-bagis brought down to its original position, thereby shutting off the flowof ink. The cylindrical colorer 0 is affixed to a tube, 0-", throughwhich the ink is conducted from the flexible tube, the colorer 0connecting with the color-bag, into a well within 0. Into this well theabsorbent material on the outside of the colorer 0 is designed to dip.Each elevation of the color-bag 0 sends a supplyof color into the wellin the colorer 0. This momentary supply in. the well maybe so ample thata part of it will overflow onto the absorbent material, and theremainder will by capillary action continue the supply to the outsidesurface; or the supply in the well may be so scant as to requirecapillary action for the entire surface-supply. The supply may beregulated by adjusting the bracket end of the link 1: in the holesshown, or by regulating the pressure of the spring 0 on the flexibletube 0 The position of the colorer o is adjustable in several ways, asfollows: Its stem 0 is circular and passes through a circular hole in apiece, 0 which piece has also a cylindrical stem, 0, passing through anupright projection, 0 of the carriage 0 Thus the colorer 0 may be pushedforward or back, turned obliquely upon the stem 0 moved to right orleft, and turned up or down upon the stem 0 appropriate set-screwsfixing it in any position.

In order to clear away from the cutting-table the pieces of paper orchips cut out by the knife, and thus allow the colorer to reach thebook, the following mechanism is provided, by which that part of thecutting-table upon which the cut is made (called the cutting-block) isdropped from its position and the chips upon it brushed off. Thecuttingblock b, Fig. 2, is made of wood, bristles packed tightlytogether, copper, or other material. It forms the top of a slidingpiece, I), sliding in ways within the frame B, and having at its lowerend a pin, b which works in the cam-slot g of the cam g. The cam g ispivoted to the frame B at 5' and is actuated by the connecting-rod gpivoted to it and also to the sector u. The cam-slot g is so shaped thatwhile the pin b is traversing one part of it the sliding piece 11remains down and stationary. WVhile traversing the next part, thesliding piece 11 ascends and carries the cutting-block b to a level withthe rest of the cutting-table Z9 before the knife has descended farenough to cut, and while traversing the third part of the slot.that is,while the knife is making the cutthecutting-block 1) re- -dropped out ofthe way.

mains stationary as a part of the cutting-table b. The colorer 0advances to apply the color while the cutting-block l) is at its lowestposition, so that there is nothing which the colorer 0 can touch exceptthe sides of the nick to be colored. By the same sliding motion of thecarriage 0 the brush 0", which is affixed to it, is carried forward overthe cutting-block l) and removes the chips.

In the machine described in my prior patent the action of the knifeitself removed the chips; but in this machine they would remain on thecutting-table, and thus hinder the action of the colorer, or furtheraction of the knife, unless removed. That is the main idea connectedwith a movable cutting-block. To allow of the colorers action, it is notnecessary to brush off the chips if the cuttingblock is So, also, othermethods of moving it may be used. Thus it is seen that the cut is madeand colored and the chips left by the knife cleared away by a continuousoperation, represented by one revolution of the pulley Any two of thesefunctions may be performed by the combination of its appropriateoperating parts in a machine which employs a different operating deviceto perform the third function. Thus the knife and colorer may act alonewithout a removable cuttingblock and a brush, as in my former patent, orthe knife and brush may act while the color is left to be applied insome other way 3 or the coloring and brushing may be done bythe devicesshown, while the cutting is performed in some other wayas, for example,by hand. The cutting-block may even be dispensed with entirely, the edgeof the leaves to be cut away lying over an. opening in the table, andthe knife being arranged to meet the edge of the table with sufficientexactness to make a clean cut.

To best distribute the cuts evenly along the length of the book, it isnecessary that it should be held in the same position upon the carriagewhile one series of cuts is being made. This might be done by hand, butinconveniently. I provide two clamps, 7', Figs. 1 and 8, upon the upperpart, c, of the carriage, between which the book is to be held. Theseconsist (see Fig. 8) of a sliding piece, '1', dovetailed upon the partc, and having a set-screw or other device, by which the sliding piece 0"may be clamped to the part c. I prefer the device shown in Fig. 8, inwhich an eccentric lever, r, pivoted to the sliding piece 0', bears downupon a flat spring, 9' and presses one end of it against the top of thepart 0 when the lever r is turned down. Being movable upon the part 0,various sizes of books may be accommodated between the two clamps. Asharp pin, 0*, enters between the leaves, and another pin, 1', sustainsthe book at its back. The pin 0 prevents the book from leaving thecarriage by sliding away from the opera.- tor, and the pin 0 prevents itfrom sliding in the opposite direction. The two thus com: bine to holdthelower part of the back of the lever r".

book fast to the carriage, back of the book above those pins is free toyield to the action of the shaping-stops as the front of the book ispresented to the knife. A piece, o pivoted or affixed to the bookclamp,is designed to hold the sides of the book upright, so that the knifewill without fail make a perpendicular cut.

In some oases it is desirable to clamp the back of the book rigidly tothe carriage. For this I employ the form of clamp shown in Figs. 14 and15, one each side of the book. The sliding piece r carries an uprightpiece, r at the edge of the carriage toward the operator. To the uprightpiece 0 is bolted a spring, 1", operated upon by the eccentric The bookbeing placed in position, the clamp is moved along the book-carriageuntil the edge of the upright piece 1*" meets it, and the spring r justslides over the top of the book when the eccentric lever r isperpendicular. The lever r is then turned down to a horizontal position.The bolts and nuts 0' and slots r allow of vertical adjustment.

The knife is so made as to afford ready vertical adjustment. In the topthereof (see Fig. 11) is a screw, m, the head of which abuts against thetop of the cavity in the shaft m, and which sustains the greater part ofthe pressure in the cutting. The set-screw 771 merely retains the knifein its position without sustaining much, if any, of the pressure. henthe knife is shortened by sharpening or the cutting-block becomes wornby use, a suiiicient turn of the screw on will adjust the knife to thecorrect position with exactness and convenience for cutting entirelydown through all the leaves. An additional fea ture which may be used ina knife of this character shown in Fig. 12, comprising a device by whichthe pieces of paper out out by the knife are automatically removed fromits interior. A disk, m, is held within the interior of the knife by aset-screw or other appropriate means, and abuts against the shoulder ofthe knife to prevent its upward movement. A second disk, 171", having astem,

m is designed to move peipendieularly within the knife. The stem mpasses through the disk m and is held from falling by the nut m upon thestem above the disk on. A spiral spring placed between the disks m and myields suiiiciently to allow the knife to do the cutting, but pressesthe disk m downward as the knife ascends with sufficient force toprevent any wedging of the paper in the cylindrical cavity of the knife.

The power which operates the knife and colorer may be appliedcontinuously; but a better way is to apply it intermittently, the knifeand colorer standing still while the operator is oscillating the tableE. Any appropriate clutch or other device to apply and shut off powerintermittently may be used. The one I have devised for this purpose isshown in Figs. 3, at, and 7. By it the operator with a motion of hisfoot can. apply the while the rest of the power, which then makes andcolors one out automatically and stops in the position from which theparts started-namely, the one shown in Fig. 2. In Fig. 4 the view isfrom 'the right-hand end of Fig. 3, and in Fig. '7

from the opposite end, Fig. 4 representingthe power as just applied andFig. 7 as it has ust been thrown off. The footlever t has one endpivoted to the frame A and the other end pivoted to a rod, 25, which isarranged to move vertically through guides attached to the frame B atthe rear of the machine. Pivoted to the rod t, or a projection thereof,is the cam t Figs. 3 and 4, and the spring i which keeps the lower endof the cam t against the rod t.

Attached to the frame B by the bolt 5 3, at a point opposite an d belowthe pulley j, is a spring, 3, upon which, at its upper end, 1s mountedthe belt-tightening roller 5-. Upon the side of the spring 5 toward thecam 1s a roller, .9 standing in the course of the cam t hen thefoot-lever t is depressed, the cam t descends, and in passing the roller3 pushes it out, and with it the spring 3, cans ing the roller 8 totighten the belt j upon the pulley j. Before the spring sis pushed outan angle-piece or stop, 5?, Fig. 4, affixed to the spring 3, standsunderneath a projection, 7 upon the pulley 3', thus preventing itsrevolution; but when the spring is pushed out to tighten the belt thestop 5 by the same movement, is released from connection with theprojection j thus leaving the pulley j free to revolve. The roller 8 iskept against the belt for a single revolution of the pulley by the stopw, which is pivoted to the frame B, and which, as the spring sis pushedout, falls out ward and downward until it is stopped in a horizontalposition by a shoulder on the spring 8, so as to hold the spring 5 inthe position given it by the action of the cam 75*. (See Fig. 4.) Thepower is thrown off at the end of the revolution by means of a pin upona pulley, j, and a system of levers which raise the stop to and allowthe spring 8 to spring back by its own elasticity, thus separating theroller .9 from the belt, and by the same move ment bringing the stop .9underneath the approaching projection j in order to stop the revolutionof the pulley j. This pin j (compare Figs. 3, f, and 7) extends from thepulley at right angles, and toward the end of the revolution strikes thelever to, pivoted upon the springs, or on any convenient part of theframe. The lever w is attached by the intermediate link, 10 to the armforming a part of the stop 20, so that when the pin 9 has reached theend of the lever w, Fig. 7, the stop w has released the springs, and ithas sprung back to its first position, leaving the parts in the positionin which they stood before the pulley j started, ready to commenceanother cut. The coiled spring attached to the frame B and to thefoot-lever 25, returns the cam t to its original position as soon as theoperator removes his foot from the footlever t. It makes no'differencewhen he does this, so far as the power is concerned. If he does it assoon as the power is applied, the cam t in its return passes in front ofthe roller .5 If he keeps it on until the revolution has been made, thecam t rotated upon its pivot, and thus passes behind the roller .9 andthe spring brings it into proper position again to begin the operation.A rod, if, pivoted to the foot-lever '6, passes through guides on theframe I and has at its upper end, ad j ustably affixed thereto, a piecet, which. extends around in front of the knife, and serves as a pressupon thebook to keep the leaves closely pressed together while thecutting and coloring are being done.

To operate the machine byhand, very little change is necessary. Ahandle, .2, Fig. 13, attached to the shaft 11?, takes the place of thepower-connections, and in that form the machine may be operated by handwithout; any further change; but to make better and more convenientoperation. I provide the stop .2", affixed to the frame II at the properplace, to limit the motion of the sector it toward the operator, andalso the spring 52, fasten ed upon the frame II and bearing against apin attached to the sector it. In order to make the cut, the operatorbrings the handle toward him until the sector it meets the stop 2, andthen in order to raise the knife, operate the colorer, and drop thecutting-block, moves the handle in the opposite direction. If he thenreleases the handle, the spring .2 serves to bring the parts back and.stop them in the best position from which to commence another out.

This same machine may be used with a little adaptation for the purposeof cutting the labels of paper, leather, or other material to be pastedupon the leaf at the bottom of each cut to protect it from wear. Thisadaptation is shown inv Figs. 16 and 17. The knife in is substantiallylike that shown in Fig. 12, but has instead of the disk m the disk in,to which is attached the bar on, as an extension thereof, extending downthrough an appropriate opening in the cutting-table Z), or over itsedge. The cutting-table is arranged without a removable cutting-block,or the cuttingblock Z) is rendered stationary at the level of the restof the table and the connecting-rod removed. A pusher, 0 in the form ofa fork, is attached to the sliding carriage o in place of the colorer.The arms of the fork are just far enough apart, that they can pass thebar m These parts are operated by the same operating mechanism whichcuts and colors the nicks. The pile of paper, 1 from which the segmentallabels are to be cut, lies under the knife against the bar m, the widthof which is made somewhat less than the width of the labels to be cut.Durin the operation of the knife and after itriscs the disk on acts as apress upon the paper and keeps the pile of labels in position until theknife has risen far enough to carry the disk m with it. The fork 0 thenadvances upon the table and pushes back the pile of labels from underthe knife.

I claim as my invention 1.. In an indexing-machine, the combination of acylindrical knife having a screwthread on its shaft with as1ipporting-frame, such frame carrying another screw-thread with whichthe screw upon the knife-shaft gears, by which the same source of powergives both rotation and longitudinal. movement to theknife,substantially as described.

2. In an indexing-machine, the combination of shaft in, having the screwm and feather-way m and carrying a cylindrical knife, the gear-wheel20*, carrying the feather H5, and the frame ll, provided with aninterior thread with which the screwm gears, by which combination thecombined rotary and descending motion is given to the knife.
